Test-case to trigger the assertion.

If I use a unsigned index type (#define EIGEN_DEFAULT_DENSE_INDEX_TYPE unsigned), all householder QR preconditioners trigger an assertion. Looking at the source it seems that the SVD code doesn't seem to be written with unsigned indexes in mind (for loops while --i > 0, etc).
